heraldry, is when the shield, or a part thereof, as a bordure, &c., is chequered, or divided into chequers or squares, in the manner of a chess-board.

This is one of the most noble and most ancient figures used in armory; and a certain author saith, that it ought to be given to none but great warriors, in token of their bravery: For the chess-board represents a field of battle; and the pawns of men, placed on both sides, represent the soldiers of the two armies, which move, attack, advance, or retire, according to the will of the gamesters, who are the generals.

This figure is always composed of metal and colour: But some authors would have it reckoned among the several sorts of furs.
